[QUOTE="winkychevelle, post: 8823992, member: 611804"] A 6inch aero is likely enough. My design is for a 13 Silverado 3500hd and will fit similarly to your box but shorter because I'm gonna add 2-3inch of foam padding on top. Box is designed for 2 nvx vcw104v3. low end is tuned to 28hz, high end 55hz and gross outside dimensions are 4.3ft³ so a big box for what's only gonna sound like 1 10 in a 6th order. I need to bust out the pen and paper and see if I can just use 1 10 instead of 2 isobaric. That makes my chamber size double but I currently have 2ft³ of just port displacement and the coupling chamber. 1 10 would need 3.5ft³ plus port displacement which would need to be less than .3ft³ to be smaller and that's doubtful. Might be worth making the box a touch longer to save money and power requirement though. As far as how to mount over the transmission hump feet going down further than the box and some strapping material to bolt to the factory seat mounts. How much higher to down fire? Probably 2.5inch They make grills for these subs so as long as the grills fit they should be fine [/QUOTE]
